Hazard Assessment of Spatiotemporal Distribution Disaster of Snowdrift on Highways
摘要
Abstract
Based on the meteorological data set of Inner Mongolia Autonomous Region from 2006 to 2020,the spatiotemporal distribution characteristics of snowdrift were analyzed.Focusing on the four core elements of highway snowdrift disaster formation:snow,wind,regional environment and highway conditions,a comprehensive risk assessment index system for highway snowdrift disaster is established by combining weighted comprehensive evaluation method with analytic hierarchy process,in order to build a mathematical model for quantitatively evaluating the potential risk of highway snowdrift disaster in Inner Mongolia Autonomous Region.The highway snowdrift disaster is divided into five levels:high risk,sub-high risk,medium risk,sub-low risk and low risk.关键词
